Thanks but I can not understand what the lazarus.pp does with the splash 
unit. I can not understand the splash unit either. I was thinking about
some easy howto for newbies about creating a splash screen. I am 
currently reading Kylix's help about creating splash screens. It tells 
me to create two forms. Set Form1's FormActivate event to do this:

if Startup then
   begin
     Startup := False;
     SplashScreen.Show;
   end;

It says that, that startup is a constant, and it's declared in Form1's 
interface part. But in lazarus there is no such constant, thus I can not 
check if startup is true or false. I tried to create that variable 
myself, like this:
var
    startup : boolean = true;

I need to give this variable a starting value, or else the 'if' won't 
work. But lazarus complains about that declaration. It says, that I can 
not use the '= true'. Why? In delphi and kylix this works fine, and this 
is (I think) a very useful feature. But if lazarus doesn't support that 
kind of declaration, then I must use something else. But I don't know 
what. Is it possible that someone would be that nice, and write me an 
example, how to do a splash screen in lazarus? That would some kind of 
christmas gift for me :)

Thanks!

Daniel
